Plastic Engineers Build Up a Sustainable Society

American Society of Plastic Surgeons and Korean Society of Plastic and Reconstructive Surgeons Society Leadership Meeting

I had the opportunity to participate in the recent 70th Congress of the Korean Society of Plastic and Reconstructive Surgeons (KSPRS) as a guest and President of the American Society of Plastic Surgeons (ASPS) in Seoul in November 2012. The purpose of the meeting was to bring common themes and ideas together between both societies. A specific leadership meeting occurred on Friday, November 9, 2...

Fast Fourier Transform Computations and Build-up of Plastic Deformation in 2d, Elastic-perfectly Plastic, Pixelwise Disordered Porous Media

Stress and strain fields in a two-dimensional pixelwise disordered system are computed by a Fast Fourier Transform method. The system, a model for a ductile damaged medium, consists of an elastic-perfectly matrix containing void pixels. Its behavior is investigated under equibiaxial or shear loading. We monitor the evolution with loading of plastically deformed zones, and we exhibit a nucleatio...

Society of Tribologists and Lubrication Engineers

A multi-scale theoretical model is presented that is the first to offer quantitative agreement with experimental measurements of selfretraction and oscillation of bilayer graphene. The model integrates density-functional calculations of the energetics driving flake retraction and molecular-dynamics simulations capturing the dynamic response of laterally-offset rough surfaces. We demonstrate tha...

Longevity of Amalgam Build-Up Restorations in Endodontically Treated Teeth

Background and Aim: Restoration of endodontically treated teeth is one of the most important and challenging topics in restorative dentistry. Longevity of such restorations is an essential factor in treatment planning. Amalgam build-up is a conservative method for restoration of endodontically treated teeth. Therefore, this study aimed to assess the longevity of this type of restoration in endo...
